TECHNICAL FIELD

The present disclosure relates to a compound for use in organicelectronic devices, such as organic light-emitting devices. Morespecifically, it relates to a compound having a novel structure ofdehydro-fused-ring, and an organic electroluminescent device and acompound formulation comprising the compound.

BACKGROUND

Organic electronic devices include, but are not limited to, thefollowing types: organic light-emitting diodes (OLEDs), organicfield-effect transistors (O-FETs), organic light-emitting transistors(OLETs), organic photovoltaic devices (OPVs), dye-sensitized solar cells(DSSCs), organic optical detectors, organic photoreceptors, organicfield-quench devices (OFQDs), light-emitting electrochemical cells(LECs), organic laser diodes and organic plasmon emitting devices.

In 1987, Tang and Van Slyke of Eastman Kodak reported a bilayer organicelectroluminescent device, which comprises an arylamine holetransporting layer and a tris-8-hydroxyquinolato-aluminum layer as theelectron and emitting layer (Applied Physics Letters, 1987, 51 (12):913-915). Once a bias is applied to the device, green light was emittedfrom the device. This invention laid the foundation for the developmentof modern organic light-emitting diodes (OLEDs). State-of-the-art OLEDsmay comprise multiple layers such as charge injection and transportinglayers, charge and exciton blocking layers, and one or multiple emissivelayers between the cathode and anode. Since OLED is a self-emittingsolid state device, it offers tremendous potential for display andlighting applications. In addition, the inherent properties of organicmaterials, such as their flexibility, may make them well suited forparticular applications such as fabrication on flexible substrates.

OLED can be categorized as three different types according to itsemitting mechanism. The OLED invented by Tang and van Slyke is afluorescent OLED. It only utilizes singlet emission. The tripletsgenerated in the device are wasted through nonradiative decay channels.Therefore, the internal quantum efficiency (IQE) of a fluorescent OLEDis only 25%. This limitation hindered the commercialization of OLED. In1997, Forrest and Thompson reported phosphorescent OLED, which usestriplet emission from heave metal containing complexes as the emitter.As a result, both singlet and triplets can be harvested, achieving 100%IQE. The discovery and development of phosphorescent OLED contributeddirectly to the commercialization of active-matrix OLED (AMOLED) due toits high efficiency. Recently, Adachi achieved high efficiency throughthermally activated delayed fluorescence (TADF) of organic compounds.These emitters have small singlet-triplet gap that makes the transitionfrom triplet back to singlet possible. In the TADF device, the tripletexcitons can go through reverse intersystem crossing to generate singletexcitons, resulting in high IQE.

OLEDs can also be classified as small molecule and polymer OLEDsaccording to the forms of the materials used. Small molecule refers toany organic or organometallic material that is not a polymer. Themolecular weight of a small molecule can be large as long as it has welldefined structure. Dendrimers with well-defined structures areconsidered as small molecules. Polymer OLEDs include conjugated polymersand non-conjugated polymers with pendant emitting groups. Small moleculeOLED can become a polymer OLED if post polymerization occurred duringthe fabrication process.

There are various methods for OLED fabrication. Small molecule OLEDs aregenerally fabricated by vacuum thermal evaporation. Polymer OLEDs arefabricated by solution process such as spin-coating, inkjet printing,and slit printing. If the material can be dissolved or dispersed in asolvent, the small molecule OLED can also be produced by solutionprocess.

The emitting color of an OLED can be achieved by emitter structuraldesign. An OLED may comprise one emitting layer or a plurality ofemitting layers to achieve desired spectrum. In the case of green,yellow, and red OLEDs, phosphorescent emitters have successfully reachedcommercialization. Blue phosphorescent emitters still suffer fromnon-saturated blue color, short device lifetime, and high operatingvoltage. Commercial full-color OLED displays normally adopt a hybridstrategy, using fluorescent blue and phosphorescent yellow, or red andgreen. At present, efficiency roll-off of phosphorescent OLEDs at highbrightness remains a problem. In addition, it is desirable to have moresaturated emitting color, higher efficiency, and longer device lifetime.

In an OLED device, a hole injection layer (HIL) facilitates holeinjection from the ITO anode to the organic layers. To achieve a lowdevice driving voltage, it is important to have a minimum chargeinjection barrier from the anode. Various HIL materials have beendeveloped, such as triarylamine compounds having a shallow HOMO energylevels, very electron deficient heterocycles, and triarylamine compoundsdoped with P-type conductive dopants. To improve OLED performance, suchas longer device lifetime, higher efficiency and/or lower voltage, it iscrucial to develop HIL, HTL materials with better performance.

The organic light emitting display device uses a hole injection layerand an electron injection layer to promote charge injection. The holeinjection layer is a functional layer formed from a single material ormore than one material. Methods involving a single material generallyutilize materials with deep LUMO levels while methods involving morethan one material are performed by doping a hole transporting materialwith a P-type, deep-LUMO material. The commonality between these twomethods is the use of deep-LUMO materials.

However, materials with deep LUMO levels are not easily synthesized dueto their substituents with strong electron-withdrawing ability, and itis difficult to possess both deep LUMO level, high stability, and highfilm-forming ability. For example, F4-TCNQ (a P-type hole injectionmaterial), although having a deep LUMO level, has an extremely low vapordeposition temperature, affecting deposition control and productionperformance reproducibility and device thermal stability; and, foranother example, HATCN has problems in film formation in devices due tostrong crystallinity, and the LUMO level thereof is not deep enough tobe used as a P-type dopant. Since the hole injection layer has a greatinfluence on the voltage, efficiency and lifetime of an OLED device, itis very important and urgent in the industry for the development ofmaterials with a deep LUMO level, high stability and high film-formingability.

SUMMARY

Devices fabricated in accordance with embodiments of the invention canbe incorporated into a wide variety of consumer products that have oneor more of the electronic component modules (or units) incorporatedtherein. Some examples of such consumer products include flat paneldisplays, monitors, medical monitors, televisions, billboards, lightsfor interior or exterior illumination and/or signaling, heads-updisplays, fully or partially transparent displays, flexible displays,smart phones, tablets, phablets, wearable devices, smart watches, laptopcomputers, digital cameras, camcorders, viewfinders, micro-displays, 3-Ddisplays, vehicles displays, and vehicle tail lights.

The materials and structures described herein may be used in otherorganic electronic devices listed above.

As used herein, “top” means furthest away from the substrate, while“bottom” means closest to the substrate. Where a first layer isdescribed as “disposed over” a second layer, the first layer is disposedfurther away from substrate. There may be other layers between the firstand second layer, unless it is specified that the first layer is “incontact with” the second layer. For example, a cathode may be describedas “disposed over” an anode, even though there are various organiclayers in between.

As used herein, “solution processible” means capable of being dissolved,dispersed, or transported in and/or deposited from a liquid medium,either in solution or suspension form.

A ligand may be referred to as “photoactive” when it is believed thatthe ligand directly contributes to the photoactive properties of anemissive material. A ligand may be referred to as “ancillary” when it isbelieved that the ligand does not contribute to the photoactiveproperties of an emissive material, although an ancillary ligand mayalter the properties of a photoactive ligand.

It is believed that the internal quantum efficiency (IQE) of fluorescentOLEDs can exceed the 25% spin statistics limit through delayedfluorescence. As used herein, there are two types of delayedfluorescence, i.e. P-type delayed fluorescence and E-type delayedfluorescence. P-type delayed fluorescence is generated fromtriplet-triplet annihilation (TTA).

On the other hand, E-type delayed fluorescence does not rely on thecollision of two triplets, but rather on the transition between thetriplet states and the singlet excited states. Compounds that arecapable of generating E-type delayed fluorescence are required to havevery small singlet-triplet gaps to convert between energy states.Thermal energy can activate the transition from the triplet state backto the singlet state. This type of delayed fluorescence is also known asthermally activated delayed fluorescence (TADF). A distinctive featureof TADF is that the delayed component increases as temperature rises. Ifthe reverse intersystem crossing rate is fast enough to minimize thenon-radiative decay from the triplet state, the fraction of backpopulated singlet excited states can potentially reach 75%. The totalsinglet fraction can be 100%, far exceeding 25% of the spin statisticslimit for electrically generated excitons.

E-type delayed fluorescence characteristics can be found in an exciplexsystem or in a single compound. Without being bound by theory, it isbelieved that E-type delayed fluorescence requires the luminescentmaterial to have a small singlet-triplet energy gap (ΔE_(S-T)). Organic,non-metal containing, donor-acceptor luminescent materials may be ableto achieve this. The emission in these materials is often characterizedas a donor-acceptor charge-transfer (CT) type emission. The spatialseparation of the HOMO and LUMO in these donor-acceptor type compoundsoften results in small ΔE_(S-T). These states may involve CT states.Often, donor-acceptor luminescent materials are constructed byconnecting an electron donor moiety such as amino- orcarbazole-derivatives and an electron acceptor moiety such asN-containing six-membered aromatic rings.
